Quantum Gravity in Everyday Life: General Relativity as an Effective Field Theory
This article is meant as a summary and introduction to the ideas of effective field theory as applied to gravitational systems, ideas which provide the theoretical foundations for the modern use of general relativity as a theory from which precise predictions are possible.
متن کاملDeformed Special Relativity as an effective theory of measurements on quantum gravitational backgrounds
Deformed or Doubly Special Relativity (DSR) [1, 2] can be understood as a tentative to modify Special Relativity (SR) in order to incorporate a new invariant scale other than that provided by the speed of light c. The idea driving this attempt is that quantum gravity effects seems to introduce a new dimensional fundamental scale given by the Planck length (lpl). This is possibly problematic for...
متن کاملThe ideas of gravitational effective field theory
I give a very brief introduction to the use of effective field theory techniques in quantum calculations of general relativity. The gravitational interaction is naturally organized as a quantum effective field theory and a certain class of quantum corrections can be calculated. [Talk presented at the XXVIII International Conference on High Energy Physics, ICHEP94, Glasgow, Aug. 1994, to be publ...
متن کاملA five-dimensional extension of general relativity and quantum theory
The torsion-free de Sitter reducible metric linear connection on a fivedimensional manifold is studied in conjunction with a method of constructing spacetime via a partially restricted reference cross section of the bundle of linear frames described in earlier publications. It leads to the equation Rαβ = (1/l)gαβ where l is a fundamental length, assumed to be the Planck length. It also yields t...
متن کاملAn effective stochastic semiclassical theory for the gravitational field
Assuming that the mechanism proposed by Gell-Mann and Hartle works as a mechanism for decoherence and classicalization of the metric field, we formally derive the form of an effective theory for the gravitational field in a semiclassical regime. This effective theory takes the form of the usual semiclassical theory of gravity, based on the semiclassical Einstein equation, plus a stochastic corr...
